用Walsh-Hadamard分析方法研究了当输入信号为二元函数时，光在渐变梯度折射率(GRIN)介质中的传输问题。用Walsh-Hadamard变换研究了GRIN介质中序列谱的演化，证实了自成像效应。
The analysis of light propagation in a tapered gradient-index (GRIN) medium when the input signal is a binary function is considered with the Walsh-Hadamard analysis. The study of the evolution of the sequency spectrum through the GRIN medium by the Walsh-Hadamard transform confirms the self-imaging effect.
